Abstract

Abstract:

There are four oil types in Pinghu structural zone, i.e. normal condensate, abnormal condensate, light crude oil and normal crude oil. Natural gas is mainly of pyrolysis product-condensate gas. Hydrocarbons produced from Pinghu structural zone are mainly of condensate gas,and then to be followed by crude oil. Reservoirs in the Huagang Formation are mainly of anticlinal type, and most of them have been cut by faults. Reservoirs in the Pinghu Formation are mostly fault block and semi-anticlinal condensate gas pools controlled by contemporaneous faults.

Key words: Pinghu structural zone, Pinghu Formation, oil and gas reservoirs
